Specification of Letters Patent.

Patented ct. 1d, i913.

Application filed January f2, 1909. Serial No.470,486.

The object of the invention is to provide' generators which can be constructed in batteries and arranged side by side and practically integral wit-h each other in order to increase the etliciency of the generators by reducing the radiation surface and the quantity of heat lost therefrom, to reduce the cost of construction by reducing the quantity of materials required and simplifying the workmanship, to reduce the space or ground area necessary .for installation, and to facilitate the operation of generators by having their working parts readily accessible and compactly uniting the several units.

The main feature of the invention consists in arranging thewater seal basins of the generators with their longitudinal axes parallel to the longitudinal axes of the grates of the generators, whereby the generators may be compactly assembled in batteries side by side, and at the same time having all of the parts readily accessible for cleaning or repair.

rlihe invention also comprises other details and arrangements of parts hereinafter described and claimed.

In the accompanying drawings Figure 1 is in part a side elevation and in part a vertical section showing one form of the generator; Fig. 2 is in part a horizontal section taken through the generator chambers, and in part a plan view of the foundation, the section being on the line 2-2, Fig. 1, Fig. 3 is a vertical transverse section on the line rl-3, Fig. l; Fig. e is a vert-ical section through the blower pipe; Fig. 5 is a longitudinal section on line 5 5, Fig. 4; Fig. G is a section similar to Fig. 4e showing a modification; Figs. 7, 8, 9, 10 and 11 are sectional views showing different forms of buckstays; Fig. 12 is in part a side elevation and in part a vert-ical section showing a modilication; Fig. 13 is a horizontal section of the same on the line 1313, Fig. 12;

and Figs. 14, 15 and 16 are cross sections of different forms of buckstays for this moditication. f

Each generator shown comprisesa generating chamber 1 inclosed by side walls Q, end walls 3, and the top or arch el. Arranged centrally in the chamber is the longitudinal grate'y 5 extending from end wall to end wall, this grate being shown as of the well knownridge type, that is, having thel two sections of the grate forming a ridge extending longitudinally through: the center of the generato-r chamber atits bottom. Open spaces G are located' at each side of this grate as is common.

Underneath the grate is a longitudinal wall 7 having a sloping top to form a ridge and located directly under the ridge ofthe grate. rlhis longitudinal ridge divides the water seal into two basins 3 vand 8, both having longitudinal axes parallel to the axis ofthe grate. These water seal basins extend outwardly beyond the end walls 3 of the generator and have the upwardly sloping bottoms 9 to facilitate the removal of the ashes as is common in generators. Heretofore the water seal basin has had its longitudinal axis at right angles to the grate, but with our arrangement the longitudinal axis of the water seal basin is parallel to the longitudinal axis of the grate, and the ash removing end portions of the water seal are located at the ends of the generators, instead of at the sides and at right angles to the longitudinal axis of the grate as heretofore.

The end walls 3 are supported on bearers 1G extending across the water seal basins and at right angles to the grate. Grate bearers 11 have their ends secured to and supported by the brick bearers 10 and intermediate their lengths are supported on cross-walls 12 dividing the water seal basins into four parts. rIhese cross walls have sloping tops as shown in Fig. 3 so as to readily shed the ashes and clinker. The grate bearers 11 are not in contact with either the bottoms of the water seal basins or with the longitudinal ridge 7, butthere are open spaces 13 between said rido'e and the lower edges of the grate bearers. Consequently clinker or ashes which pass through the grate are shed by the cross ridge 12 and longitudinal ridge 7 and directed into the water seal basins from which theyare removed with the ashes and clinker passing down at the sides of the grate, so

that no separate cleaning of the space'underneath the grate is necessary as inrprior constructions.

By the construction described and particu-. larly by having the longitudinal axis of the Water seal basins parallel to the longitudinal axis of the grate so that the ashes are removed at the ends instead of atthe sides: of the generators, itis possible to assemble a number of such generators in a battery in very compact form, the side walls being in contact, or preferably a common dividing wall being provided for adjacent generators. This can be done without interfering with the accessibility oI" any of the parts, the` ashes being removable from the ends of the@ individual generators, or what may be]` termed the side of the battery, the fuel being suppliedthrough the hoppers 15 in the topf` or arch of the generator, the gas beingi drawn oli' through outlet 16 in an end Wall. of the generator, and the blowers 17 being applied through the end walls'so as to blow into the space underneath the grate. All of these parts are readily accessible notwithstanding the placing of a series of generators in battery form as shown.

Preferably two blowers 17 are employed, one at each end of the grate. These blower pipes are extended into the brick work so as to direct the full force of the blast into the space underneath the grate and not permit leakage up through the brickwork. This may be done as shown in Fig. 6 in which the blast pipe 17 is provided with a flange secured directly to the shell 18 and providing a sleeve or extension 20 also preferably secured to the shell and extending entirely through the brick work; or as shown in Figs. l and 5 in which doors 21 are provided in the brickwork at the ends of the grate in order to give access to the space underneath t-he grate without going through the water seal basin. 1n this arrangement blast pipes 17 are each provided with a flange 22 secured to the door and with an extension 23 projecting through an opening in the door and extending to or into close proximity to the inner tace of the brickwork. By this -arrangement the air supply pipe is carried practically to the end of the grate.

The individual generators may be either rectangular in cross-section with iiat end walls, as shown in Figs. 1 to 3, or may be somewhat oval in shape, or with curved end walls as shown in Figs. 12 and 13. In either form, however, the side walls are common to two adjacent generators.

1n Figs. 1 to 3 the'shell 18 is formed from plates running vertically from top to bottom and having vertical joints at 25. The connecting means at these joints form stiiteners or buckstays extending from top to bottom and giving the necessary strength or stiltness to the shell.

In Figs. 1 and 2 the buckstays are shown formed of a pair of angle bars 26 riveted to the edges of the plates and serving as a means for connecting adjacent plates. Similar angle bars may be riveted to the plate between its edges either vertically or diagonally as may be desired in order to stitl'en the plate between its edges, or if desired the plate may bebuckled, corrugated or other wise bent to secure the same effect. The shell of the sides of the end generators of the battery may be curved-or straight with buckstays 27 to stiiiien the the plates. f Y

Fig. 7 shows the buckstays :termed by means of an angle bar 26 and a Z bar 28 with the transverse plate 29 interposed between the same. Fig. 8 shows the same construction but with the transverse plate 29 omitted. Fig. 9 shows a channel bar 30 secured to the edges of the shell plates 18. Fig. 10 shows buckstays formed of a Z bar 31, a welt 32 being applied on the inner face to close the joint. Fig. 11 shows the buckstay formed by a T iron 33.

Figs. 12 and 13 show the ends of the units or generators curved and the shell 34 of similar form. This curved shape ot the shell gives the necessary stiffness. The edges of the plates 34; are secured to the vertical buckstays 35. These buckstays may be either channels, as shown in Figs. 9 and 14, or may be composed of two angle bars 36 as shown in Fig. 15, or of an angle trough shaped bar as shown at 37 in Fig. 16. The side walls of the generators which form the ends of a battery are made ot the same thickness as the end walls of the individual generators. V

1n Figs. 1 to 3 the plates which form the shell oi the ends of the individual generators, or the side of the battery are rigidly connected and form a continuous plate for the entire length of the battery and thereby -form a tie to resist the'thrust due to the arches which form the roofs of the end generators in the battery. The shell on opposite sides of the battery is connected at intervals by suitable tie members extending through the walls or partitions between adjacent generator chambers. Fig. 2 shows the tie members consisting of plates 29 extending from top to bottom and having their edges secured between angle bars 26 torming the buckstays. These plates separate the brickwork or lining of two adjacent chambers, so that the lining in one chamber can be removed and replaced without interfering with the adjacent generator.

1n Figs. 12 and 13 the transverse tie members consist of rods 38, extending through spacing tubes 39 and connected to same and oin the buckstays. In this form the rods are located only at intervals from top to bottom and do not divide the partition wall between adjacent generators.

rlhe construction of the walls and shell of the generators described can be applied to generators with solid bottoms and without water basins, and also to generators provided with means for the recovery of byproducts. Poke holes 40 are provided on each end, such poke holes being located adjacent .t'o 'each of the sloping sides of the grate 5. These poke holes on the exterior are circular, but flare toward the inside, the flare being in a line parallel to the sloping faces of the grate so that the poker can be made to sweep over the entire surface of the grate and remove any clinker that may adhere thereto. basins are connected by channels or gutters 42 which preferably are open gutters as shown and which serve to maintain a uniform water level in the basins of all the generators of the battery. A water supply t3 is provided at either or both ends of the battery, the communications between the water seal basins making it unnecessary to supply water to each basin.

The generator described has all of the working parts easily accessible. The several generators are compactly arranged, thus not only reducing the ground area necessary for the installation of generators of a given capacity, but also facilitating their operation. The efficiency of the generators is increased because of the reduction of the radiating surface, there being no radiation from the side walls of the generators except the two end ones of the battery. This conserves a large amount of heat that has heretofore been lost and to that extent in creases the efficiency. The cost of construction is also reduced on account o-f having dividing walls which are practically common to two adjacent generators. rlhis reduces the amount of material and on account of the plain and substantially rectangular shapes of the generators the workmanship is simplified and reduced and there is little loss in cutting the plates.

W e are aware that heretofore it has been proposed to arrange generators in a battery, but in such prior constructions the generators have been of general oval forni with the walls of the units united for only a short distance, so that the radiating surface is only very slightly decreased over the individual system. Furthermore, in these prior constructions the water seal basins have always been arranged with their longitudi` nal axes at right angles to the longitudinal axes of the grates, thus necessitating the location of the axes of both the grate and the water seal basins diagonally with reference to the line connecting the centers of The several water sealv the individual generator walls except for short distances, but also located the ends of the 'grates and the ends of the water seal basins in such position with reference to the adjoining generator that the parts were not readily accessible and particularly was it inconvenient to remove ashes. By our construction in which the longitudinal axes of the water seal basins are parallel to the longitudinal axes of the grates, it is possible to have both of these at right angles, or substantially so, to the line joining the centers of the individual generators or units composing the battery. The consequence is that all working parts are exposed and readily accessible and the units can be placed in contact along their entire sides, thus greatly reducing and simplifying the cost of construction, reducing the amount of radiation and also reducing the required ground area as compared with prior battery constructions.
